See All the 2015 Billboard Music Awards Winners

The 2015 Billboard Music Awards took over Las Vegas on Sunday (May 17), and while there were many winners, it was Taylor Swift's night. After kicking things off with her much-hyped "Bad Blood" video premiere, she took home awards for Top Billboard 200 Album, Top Billboard 200 Artist, the fan-voted Billboard Chart Achievement Award, Top 100 Hot Artist, Top Digital Songs Artist, Top Streaming Song (Video), Top Female Artist and Top Artist. Her rumoreddefinite boyfriend-type-person Calvin Harris also won an award for Top Dance/Electronic Artist, though his acceptance didn't make the telecast.

One Direction took home two awards as well, and dedicated their Top Duo or Group honor to their "brother" Zayn Malik — which means the boys have moved onto the "I remember our time together fondly, and I hope you're doing well" part of their breakup with the departed fifth member.
